Ok, as noted in general talk, i recently got my g scale dash 9 locomotive I would like to know bar none, which is the best sound chip to get. pheonix/lionel etc.. I know nothing about these. I'd like to custom modify this loco and add my own speaker to it. I was thinking about the bottom, close to the fuel tanks or something. I'd like it to have as much bass as possible. Also, I'd like to be able to rev the sound while it's in idle, play with the bell etc.. I don't want sounds overlapping one another. (i think this requires DCC, I'm not sure if the layout will be track or battery) Thanks!
